Abstract Adherence to the American Cancer Society’s (ACS) Nutrition and Physical Activity Cancer Prevention guidelines is associated with lower overall cancer risk and mortality among U.S. adults. Prior studies of ACS guideline adherence have relied on self-reported leisure physical activity (PA), which shows low correlations and may inaccurately estimate objectively assessed activity in Hispanic/Latino adults. We examined variations in guideline adherence score and levels according to how moderate to vigorous (self-reported and accelerometer-measured) physical activity (MVPA) was operationalized in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) cohort. Data were from 16,415 adults enrolled in the HCHS/SOL between 2008-2011 from the Bronx, Chicago, Miami and San Diego. Following ACS guidelines, we categorized dietary scores (derived from quartiles of proportion of whole grain, quartiles of red and processed meat, fruit &amp; vegetables (&amp;lt;5, ≥5 servings/day), and tertiles of total carotenoids), alcohol intake, physical activity, and body mass index (BMI). Behaviors were scored from 0 (least adherent) to 2 (most adherent): BMI &amp;lt; 25, 25 to &amp;lt;30, or ≥ 30 kg/m2; 0-2, 3-6, 7-9 diet points; no alcohol, &amp;gt;0 - ≤1 drink/day women/0- ≤2 drink/day men, more alcohol). PA was operationalized as: (1) self-reported leisure and (2) accelerometer-measured MVPA as 0 mins/week, &amp;gt;0 to 150 mins/week of moderate activity or &amp;gt;0 to &amp;lt;=75 mins/week of vigorous activity, &amp;gt;150 mins/week moderate activity or &amp;gt;75 mins/week of vigorous and (3) self-reported total (leisure, work, and transportation) MVPA as &amp;lt;8.75 MET-h/week, 8.75 to 17.75 MET-h/week, &amp;gt;17.5 MET-h/week. Components were summed with possible range of “0” (does not meet recommendations) to “8” (meets all recommendations), and further categorized as low (0-3), moderate (4-5), and high (6-8) adherence. Weighted Chi-square tests compared the three scores. Overall mean ACS guideline adherence ± standard error (SE) was 3.7 ± 0.03 when using leisure-MVPA, 5.3 ± 0.02 for total-MVPA and 4.0 ± 0.2 for accelerometer-measured MVPA. Percentages for low, moderate, and high guideline adherence differed by PA measure used: self-report leisure-MVPA (49.4%, 40.1%, 10.6%, respectively), self-report total-MVPA (14.9%, 40.8%, and 44.3%, respectively), and accelerometer-measured MVPA (33.2%, 53.2%, and 13.6%, respectively). Differences were found for leisure vs. total-MVPA (p=0.000); leisure vs. accelerometer-measured MVPA (p=0.000); and total vs. accelerometer-measured MVPA (p=0.000). Level of ACS guideline adherence among Hispanic/Latino adults is dependent on how MVPA is measured and operationalized. Our study demonstrates potential misclassification in the level of ACS guideline adherence in studies operationalizing ACS adherence scores based solely on self-reported leisure MVPA data for this population.
